The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Moreover, studies have also investigated simultaneous ionization and excitation processes, revealing significant differences in the angular distribution of ejected electrons depending on the type ...

In LED bulbs, light is produced almost directly by the movement of electrons jumping from one energy level to another in a process of ionization and excitation. But who knows what will replace ...

Current hot topics of research worldwide include positron-induced ion production (comprising ionization with and without Ps formation, annihilation, etc), positron impact excitation (vibrational and ...

once they come to terms with this excitation. Break-up of a committed couple would be analogous to ionization of the hydrogen atom into a proton and an electron. A large amount of external ...

Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Y&R’s Melody Thomas Scott Promises Nikki’s Nightmare Isn’t Over Jan 11, 2024 The Young and the Restless Y&R’s Lauralee Bell, Michael Damian, and Michelle Stafford Are Back at it Again! Oct ...

We investigate the over-barrier ionization of hydrogen atoms in intense circularly and elliptically polarized laser fields. By solving the time-dependent Schrödinger equation, we simulate the ...

The characteristics of plasma cleaning technologies with different excitation methods, such as direct current discharge, low-frequency discharge, radio frequency discharge, and microwave plasma ...
